How to set up SPAN for a vlan Interface

Hi,

I am trying to capture traffic for a particular VLAN. I tried to do the following:

Torsaa-mls1(config)#monitor session 2 source interface vl

Torsaa-mls1(config)#monitor session 2 source interface vlan1

                                                       ^

% Invalid input detected at '^' marker.

.....

So VLAN are not supported. Is there any other way to accomplish this?

Thanks

Re: How to set up SPAN for a vlan Interface

The 3560 does support vlans as the source. I think it may be your configuration ie. -

Torsaa-mls1(config)#monitor session 2 source interface vl

Torsaa-mls1(config)#monitor session 2 source interface vlan1

don't use the interface and vlan commands together. The command syntax is -

"monitor session source vlan "
